Abstract: A method and apparatus are described for supporting a two-stage device-to-device (D2D) discovery using a D2D interworking function (IWF). A D2D IWF component may be configured to perform mapping between an application running on an application server and a third generation partnership project (3GPP) network, and provide a set of application programming interfaces (APIs) to allow discovery to be provided as a service to D2D applications. An application identifier may be mapped to a 3GPP identifier. Further, a method and apparatus are described for performing client-server discovery. A first wireless transmit/receive unit (WTRU) may be configured for a listen-only operation, and a second WTRU may be configured to transmit beacons. The first and second WTRUs may perform a radio access network (RAN) discovery procedure at an access stratum (AS) layer. A method and apparatus for performing charging for D2D service using a D2D IWF are also described.

Abstract: A method includes after receiving a first non-access stratum (NAS) security mode command (SMC) message sent by an initial access and mobility management function (AMF), a user equipment (UE) stores a first NAS security context; the UE receives a second NAS SMC message sent by a second AMF, where the message carries indication information used to indicate the UE to use the first NAS security context; and the UE uses the first NAS security context as a current NAS security context based on the indication information. According to the method for mobility registration provided in this application, when receiving the second NAS SMC message sent by the second AMF, the UE uses the first NAS security context as the current NAS security context, and then processes the second NAS SMC message, so that the NAS security contexts on the UE and the second AMF are consistent.

Abstract: A method for processing a non-access stratum context is as follows: A terminal device sends a registration request message to a first public land mobile network PLMN. The terminal device receives a registration accept message from the first PLMN. When the terminal device deregisters from the first PLMN over a first access network, the terminal device stores, in a storage medium of the terminal device, a first PLMN identifier of the first PLMN and a first NAS security context established by the terminal device with the first PLMN. Embodiments of this application are used for a processing process of the non-access stratum context.

Abstract: A method for registration is used in an access and mobility management function (AMF) redirection scenario. The registration method includes determining, by a first AMF selected, during AMF redirection, to serve a user equipment (UE), to protect a first message, and sending the protected first message to the UE, where the first message includes an authentication request message.

Abstract: A key obtaining method includes sending, by an authentication server function (AUSF), an authentication service request message to a unified data management (UDM) function. The method also includes receiving, by the AUSF, an authentication service response message sent by the UDM function. The authentication service response message includes first permission information. The first permission information is used to indicate to generate a key KAKMA for user equipment (UE). The method further includes generating, by the AUSF in response to the authentication service response message, the KAKMA and a key identifier (KID) corresponding to the KAKMA. The method additionally includes sending, by the AUSF, the generated KAKMA and the generated KID to an authentication and key management for applications anchor function.

Abstract: Embodiments of this application provide a connection resume method and an apparatus. The method includes: A terminal device sends a first message that carries first indication information to a first network device. The first indication information is used to indicate to calculate a resume MAC value based on a first parameter set. The first parameter set includes one or more of a resume cause value or an RRC resume request message. The terminal device receives a second message from the first network device. When the second message carries second indication information, the terminal device sends an RRC resume request message that carries the resume MAC value to a second network device. The second indication information is used to indicate to verify the resume MAC value based on the first parameter set.

Abstract: Embodiments of this application disclose an air interface information security protection method and apparatus, to protect security performance of air interface information sent by a terminal to a base station. in an embodiment, a terminal determines a first message authentication code (MAC) value based on a security key and air interface information, where the security key is a non-access stratum (NAS) security key between the terminal and a core network device; and the terminal sends the air interface information and the first MAC value to a base station.

Abstract: This application provides a method and an apparatus for mobility registration, where the method includes: After receiving a first NAS SMC message sent by an initial AMF, UE stores a first NAS security context; the UE receives a second NAS SMC message sent by a second AMF, where the message carries indication information used to indicate the UE to use the first NAS security context; and the UE uses the first NAS security context as a current NAS security context based on the indication information. According to the method for mobility registration provided in this application, when receiving the second NAS SMC message sent by the second AMF, the UE uses the first NAS security context as the current NAS security context, and then processes the second NAS SMC message, so that the NAS security contexts on the UE and the second AMF are consistent.

Abstract: Embodiments of this application relate to a registration method and apparatus to ensure that user equipment does not discard and processes a received authentication request message sent by a target AMF. In the registration method, an initial AMF sends indication information to the UE, or the target AMF sends, to the UE, the authentication request message that includes indication information, where the indication information is used to indicate the UE to delete an NAS security context. The UE deletes the NAS security context, processes the received authentication request message, and sends an authentication response message to the target AMF. Alternatively, the UE directly processes a received authentication request message without security protection, and sends an authentication response message to the target AMF.

Abstract: A communication method and a related product are provided. The communication method includes: When UE switches from a source slice to a target slice mutually exclusive with the source slice, both the UE and a target AMF serving the target slice can obtain a first AMF key Kamf_new. The first AMF key Kamf_new is different from a second AMF key Kamf, and the second AMF key Kamf is a key of a source AMF serving the source slice. According to the application communication security and effectiveness are significantly improved_in a mutually exclusive slice switching scenario.

Abstract: A model for automated item generator of the graphic intelligence test solves the tremendous time consuming problem for manually devising the graph intelligence item. At the same time, the invention can automated generate more complicated, more transformations and better layout graph for intelligence test, which are hard to predict. The model utilizes the 12 branch tree as the expressing pattern of matrix graph item, and 8 branch trees as the expressing pattern of series graph item. The automated generating item methods have been presented, and the difficulty of the item has also been validated with the similarity of the optional answers and difficulties of the rules and complexity of the sub-graph. The best feature of the model is that a big amount of the graph item for intelligence test can be generated at one time by the computer, instead of manually devising the matrix graph or series graph for intelligence test.
